FLY TERMINATOR.

ll'o Drawing.

My present invention is an insecticide, and a method of preparing and using the same, it being an especial object of this invention to mitigate the fly nuisance.

It is an object of this invention to provide a liquid adapted to be vaporized, within a room or elsewhere, in such manner as to reduce a prompt effect in the killing of flies or other insects; and in a preferred form of my invention, I prepare and employ an extract of pyrethrum in a volatilizable or anic liquid, such as gasoline.

t is a further object of this invention to provide a liquid which may be sprayed or evaporated into the air in such manner as to promptly destroy such insects as may breathe the same, although having no appreciably harmful or unpleasant effects upon higher forms of life, such as human beings; and I may associate with or incorporate in my volatile insecticidal li uid, containing an active principle adapte to kill such insects as may breathe the same, any desired perfume or deodorizing material, the choice of a deodorant or erfume being ordinarily dependent upon t e place where my insecticide is to be used, it being within the scope of my invention to incorporate within my volitilizable liquid, when the same is to be used about a butcher shop, or the like, a material which shall impart thereto the odor of smoked meats-this being merely an example of the method by which I ma adapt my composition to use in a articu ar location or environment.

It is believed that the eneral character of my invention may be ful y understood from i the following description of an illustrative embodiment thereof:

To prepare a gallon of my insecticidal liquid, I may admix one-half ound, more or less, of pyrethrum, preferab y in a powdered form, with one gallon of a suitable solvent such as coal oil, gasoline, or another mineral oil having the c aracteristic of be ing readily volatilized when sprayed in minute particles at ordinary temperatures and atmospheric pressures and I may permit the resultant suspension to stand, ordinarily without an ap lication of heat thereto, during forty-eig t hours, more or less, and durin this time the mixture may advantageouslya stirred two or three times, or more frequently. At the end of the peri- Applieation filed April :38, 1938. Serial No. 884,116.

od referred to the residues of yrethrum having referably been permitte to settle, I may raw off or otherwise separate the supernatant liquid therefrom and this li uid is suitable for use, with or without the a dition of a deodorant or erfume, for the destruction of flies or the like; and, for the urpose last referred to, cinnamon odor may e used when my insecticide is to be employed in bakeries, and violet odor may be used when the same is to be used in private residences.

To produce a rompt and reliable efl'ect in the killing of ice, the insecticidal liquid referred to being easil volatilized I may produce a vapor thereo in any suitable way, as by the use of an ordinary atomizer or spray pump, substantially equivalent results being also obtainable by a vaporizatron of the mentioned liquid in a suitable vessel or u on a surface.

The resu ts obtained by the use of m insecticidal liquid are striking and a vantageous in the highest degree, it being commonly possible, by the procedure above indicated, to practically eliminate flies from a butcher shop or the like, within a period of five minutes, the result sometimes being a visible accumulation of dead flies upon a floor. These results being obviously not dependent upon any entrance of oisonous material through the mouths of the insects destroyed, I attribute the immediate and surprising efiects mentioned to the breathlng of m insecticide by the flies or other insects w ich it destroys.

Applicant is aware of the use of pyrethrum as an insecticide and of the fact that it has been utilized in some cases in solution in water, in an emulsion with kerosene and also in certain roportions with alcohol. Such uses however, liave been to spray plants or the like with the solutions, the object being to apply the pyrethrum as well as the conveying vehicles directly to the insects or to have same retained on the plant so that the insects will contact therewith.

Other methods of using pyrethrum have been in the form of powders, either pure or diluted with other owdered materials. The pyrethrum has a 0 been burned for use in fumigation, either directly or by mixing with some combustible or more or less inert substance. However, these features are altogether different from applicants invention, a characteristic feature of which is that the active principle of pyrethrum is held in solution or suspension in a mineral oil having such characteristics as would be readily volatilizable when sprayed in minute particles in the air at ordinary temperatures and atmospheric pressures; thus distributing the pyrethrum in volatilized form in the air.

Although I have indicated above the preferred composition of my insecticide, and preferred modes of preparing and using the same, it will be understood that various features of my invention might be independently employed, and that various modifications might be made therein without departure from the spirit and scope of my invention, as the same is indicated above and in the following claims.

What I claim is:

1. A liquid fly and insect repellent, comprisin a clear homogeneous liquid consisting 0 kerosene and the volatile active principles of pyrethrum.

2. A liquid fly and insect repellent comprising a clear homogeneous mineral oil and the volatile active principles of p rethrum, said oil being readily volatizahl-e when sprayed in minute particles in the aira't ordinary temperatures and atmospheric pressures.

3. In the pre aration of an insecticide, the method which comprises extracting pyrethrum in a mineral oil solvent, in the proportions of about one half pound pyrethrum and one gallon of the solvent liquid, such solvent being readily volatilizable when sprayed in the air in minute particles at ordinary temperatures and atmospheric pressures.

In testimony whereof I have signed my name to this specification.
